IMPROVEMENT IN SULKV-PLOWS.

Specification forming part of Letters Patent No. 132,772, dated November5, 1872.

To all whom it may concern:

Be it known that I, CHARLES N. OWEN, of Salem, in the county ofOolumbiana, State of Ohio, have invented a new and useful Improvement inSulky-Plows, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawing making partof this specification, in which- Figure l is a perspective view of myimproved sulky-plow, and Figs. 2,3, and 4 are detached views ofdifferent parts thereof.

Similar letters of reference denote correspondin g parts in all thefigures.

The first part of the invention relates to combining, with a plow-beamwhich is mounted upon wheels by means of a vertical pivot or itsequivalent in such manner that said beam can vibrate horizontally, anadjustinglever operated by the driver, to regulate and control theposition of the beam relative to the line of draft, for the purpose ofcausing the plow to run to or from land. The second part of theinvention relates to mounting the plow upon the wheels by means of ahanger which can be adjusted laterally in order to provide for plows ofdifferent widths or for any change which may be requisite in adapt- Theinvention further relates to certain details of construction, as will befully explained.

In the drawing, A A are the wheels, one being partly broken away to morefully show certain devices. B B G O constitute a crankaxle, G 0 being abracket or arch, the vertical portions 0 of which are provided withsockets to receive and support the upright arms B of the axles. Inpractice I usually make the arch of cast-iron and make the socketssquare; then, by making the axles square also, so that they will notturn in the sockets, their vertical position being adjusted byset-screws c, a cheap, convenient, firm, and durable crank-axle isconstituted. When preferred, the cast part may be made malleable. Iusually make the horizontal arm of the axle of the land-Wheel theshortest of the two, and make the vertical arm of the same axle thelongest; but I do not wish to be limited to any specific construction ofthese parts. D is the plow-beam, and

v D the plow. I have not shown the plowhandles, but these may be of anyusual or desired description. D D is a yoke pivoted to in g leverpivoted to pawl 0 and relative arrangement of segment E, cog-' thecrank-axle and extending rearward. One arm, D of this yoke extendsforward and is employed as a foot-lever to assist in lifting the plow. Eis a toothed segment attached to the yoke. E is a similar segment or acog-wheel mounted on a stud or spindle projecting from the crank-axleand engaging with segment E. E is a ratchet-wheel formed in one piecewith or secured to cog-segment E. F is a liftinglever vibrating aboutthe same pivot with wheels or segments E E F is a thumb-lever operatinga weighted pawl, f, pivoted on lever F, and engaging with ratchet E Asthe construction and operation of the foot-lever, the hand-lever, andtheir connect-in g devices is fully explained in a patent alreadygranted to me, they need not be more explicitly set forth here. 0 is aratchet-segment formed upon or secured to the upper portion of thecog-wheel E 0 is a pawl mounted either upon the bracket 0 G or upon anarm rising therefrom. e is a weighted tripping and lock- Theconstruction wheel E ratchet E and ratchet-segment e and pawl e areplainly shown in Figs. 2 and 3. The plow-beam D is mounted upon thetransverse bar forming the closed end of the yoke D D by means of ahanger, G, in such manner as to vibrate freely thereon. H is a vibratingangular plate, the vertical flange of which is pivoted to hanger G at g.I is a tlat plate pivoted to the horizontal flange of plate G at i. g gare set-screws working in projecting ears or hangers G, and engagingwith the horizontal portion of the vibrating angular plate H on oppositesides of the pivot g. By depressing one screw and elevating the other,plate H and the plow may be caused to oscillate about pivot y as acenter, thus changing the position of the land-side relative to aperpendicular line, as will be readily understood without furtherexplanation. Hanger G, and of course the plow, may be adjusted laterallyupon the yoke by means of pins inserted in perforations d. K is thetongue; L is the seat; these parts being of any usual or desiredconstruction. M M is a treadle-bar or drop-iron sliding vertically in aslot in the tongue. The T-piece M is intended to en gage with theplowbeam and regulate its vertical position, as in myearlier patent, forwhich reason itis provided rrron.

with a sliding stop, m,- but in this new treadlepass down at each sideof the plow-beam near its front end. a n are footrests projecting fromeach side of lever N.

The driver while riding in his seat can by means of his feet guide anddirect the plow at will through lever N. When the operator desires tolift the plow and hold it in an elevated position he places the weightedlever or balance e in the position shown in the drawing, when, as it islifted by means of either the hand-lever F or foot-lever D, the pawlwill be caused to engage with ratchet c and lock the plow wherever it isplaced. As soon as the weight of the plow is thrown upon the pawl thebalance 0 is reversed, as in dotted lines, Fig. 2. Under thislast-described arrangement, it the plow be lifted by either of thelevers, the ratchet 6 will be withdrawn from segment 6, leaving the plowfree to drop to the ground. Thus it will be seen that the operator canwith one hand only let the plow down after it has been locked in anelevated position. In plowing ground having a very smooth surface it issometimes found advantageous to lock the plow at suchheight as shallinsure a proper depth of furrow, thus relieving the sole of muchfriction and materially lessening the draft. The plow may be adjustedlaterally on the rear bar of the yoke to regulate the width of thefurrow, to keep it (the plow) in line when three horses are used,

or to compensate for the difference in width of plows or beam.

By making both axles adjustable in the bracket 0 O, and making the plowadjustable laterally, I provide for adapting it for either a right orleft hand plow by merely reversing the positions of the wheels, andcanalso adapt the sulky to plows of different heights. The

leverN might be pivoted to the tongue instead of the drop-iron M but Iprefer the construction shown, as pivoting to the tongue would require agreater length of legs in order that the plow-beam should not escapefrom between them during its rising and falling motions.

Although I have shown the laterally-adjustable hanger G in combinationwith a vibrating yoke, yet I do not wish to be confined to thisconstruction, because many of the advantages incident to this lateraladjustability may be derived by applying this part of my invention toother sulkies.

The plow can be bolted directly to plate H instead of to plate I, andyet have its landside adjustable by means of set-screws y, although Iprefer the construction shown, as it allows the desired freedom oflateral movement in the plow-beam.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a sulky-plow, the combination, with the forward end of theplow-beam, of a footlever arranged within reach of the drivers feet forvibrating said plow-beam in a horizontal plane independently of thecarriage to cause the plow to run to or from land, substantially asdescribed.

2. In a sulky-plow, I claim the combination of the yoke 1)" D thelaterally-adjustable hanger G, the plow, and its connecting devices forpivoting and adjusting said plow to the hanger G, all substantially asdescribed.

3. The combination of ratchet-segment e, the pawl 6 and the weightedlever or balance 0 with the cogged wheel E coggcd segment E, the yoke,and operating devices, substantially as described.

4:. The combination of the hanger G, the pivoted angular plate H, andset-screws g for adjusting the position of the land-side, substantiallyas described.

5 In combination with the drop-iron or treadle M M, the adjustablesliding stop m, substantially as described.

6. The combination of the adjustable bracket 0 G, to which the yoke D Dis pivoted, with the angular stub-axles B B, having the open spacebetween their inner ends to permit the free vertical adjustment of theplowbeam, substantially as described.

In testimony whereof I have hereunto set my hand this 3d day of July, A.D. 1872.
